In Class Exercise, Spring 2012
We have two data files, from the
2.1 database, which was a European Union
project to gather climate data from ship log books. These two files
contain extracts from the data base for a British ship.
- Winds as reported daily in the ships
- Ship velocity as reported from the
differences in daily position, generally at noon, in the logbooks.
You will produce the following in Matlab:
- "Map" showing the route of the ship. This does not have to be very
pretty (just a plot of Lat versus Long), but if you have time, you should
see if you can get a nice map with Matlab.
- Sticks/tadpole plot of the observed winds and the ship velocity for the
entire period covered by the log. You can either put these on the same
plot, or make two plots and place them one above the other so they can be
- An improved version of the plot that better shows the underway time.
- A table with the wind speeds above 19 knots, showing the location, date,
and the wind vector.
- A diagram showing the correlation between latitude and wind speed, with
the computed correlation coefficient. If this is too simple for you,
get a correlation between wind speed and ship speed.
You can do any preparation and manipulation of the two data files in any
program you want (Excel, Word, or Notepad).
Paste the graphics and table into Word, and append you m-file.
If you have to, make and document any assumptions you need to proceed.
